Title: Method and a device for casting concrete products
Inventor: OJANEN PAAVO
IPC: B28B15/00
Filed: 1989-12-29
Abstract: Abstract This invention relates to a method and a device for  casting  elongated  concrete  products.  In prior art methods a mould (1) is filled up with flowing concrete material,  which is then com-pacted. This technique is slow and the strength of the end result cannot be relied on. these drawbacks are eliminated by carrying out the compaction of the concrete material first in a compaction tank (3), whereafter the concrete is fed by means of a pump (2) into the mould (1) as a continuous flow in such a way that the con-crete moves on in the mould in the longitudinal direction of the mould.

Title: Movable-coil electrodynamic transducer diaphragm
Inventor: CESATI MARIO
IPC: H04R31/00
Filed: 1990-05-10
Abstract: " MOVABLE-COIL ELECTRODYNAMIC TRANSDUCER DIAPHGRAM "     ABSTRACT         The present invention relates to a diaphgram for an electro-acoustical transducer, of the movable-coil electrodynamic type, for transforming electrical signals into acoustical signals and diffusing the electrical signals, characterized in that the diaph-gram comprises a single-piece blade member, made of a metal material of very low density and very good heat conductivity  and mechanical characteristics.       The metal blade is resiliently suspended on the perimeter thereof, is metally coupled to the unit of which it forms a portion, and supports the acoustical current wire fixed at the center of mass thereof to the active metal surface.       The acoustical current conductor wire communi-cates to the blade the heat which is produced by the acoustical current, which is added to that generated in the blade mainly because of the deformation of the resilient suspension.       This generated heat is quickly absorbed by the metal blade and efficiently dissipated by irradia-ting it into the encompassing air and by conduction through the adjacent masses, thereby holding the tempe-rature under a danger level.

Title: Drainage valve having a flexible flap with an edge taper
Inventor: PROULX SERGE L
IPC: F16K15/03
Filed: 1990-08-08
Abstract: A valve is installed into an underground conduit to control drainage of water through that conduit.    The  drainage  control  valve  includes  a perforated plate across the conduit.  The latter plate is formed with a peripheral groove rectangular in cross section and a hollow tube made of flexible material is inserted into this groove to seal the joint between the plate and the inner surface of the conduit.   A flap also made of flexible material is applied against the upstream surface of the plate and is  formed  with  a  peripheral  edge  taper  whereby pressure applied on the flap by water upstream of the drainage valve  forces the edge taper against the upstream plate surface to form a sealed joint between these flap and plate.  The upper portion of the flap is attached to the upper portion of the plate through screw and nut assemblies.  These assemblies traverse rigid washers inserted in respective holes made in the flap.  The flap is slightly thicker than the washers for preventing excessive crushing of the  flexible material  upon  tightening  of  the  screw  and  nut assemblies while ensuring water imperviousness.   An elongated member integral with the flap has a free end formed with a hole to attach a cord enabling lifting of the lower portion of the flap to thereby drain water through the perforated plate.

Title: Aromatic polyester moulded compacts
Inventor: FIALLA PETER
IPC: B29C43/02
Filed: 1991-02-04
Abstract: (57) Abstract Sintered compacts made of aromatic polyesters, produced from diphenols such as 1,1-bis(4-hydroxyphenyl)-1-phenyle-thane or 9,9-bis(4-hydroxaphenyl)fluorene, as well as phthalic acid halides, have one or several glass transition temperatures be-tween 220 and 400 °C and a tensile strength above 40 N/mm2, preferably above 60 N/mm2. In order to produce the sintered compacts, the polyester powder is subjected to a pressure above 3000 N/cm2 in a closed mould. The mould is slowly heated, then maintained for a longer period above the glass temperature and slowly cooled down once again. While it cools, pres-sure can be reduced. Cross linking occurs in the polyester mass during sintering, increasing the fastness to solvents. These sintered compacts are generally useful as semi-finished products or preformed prefabricated elements, from which the de-sired articles can be produced by machining.
